Specification of Letters Patent;

Application filed February 10, 1906. Serial No 300.409.

Patented Jan. 15, 1907.

To all whom it may concern.-

Be it known that I, HENRY M. SoIPLE, a

' citizen ofthe United States, residing at San fication.

Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Sectional Poles for Telephone, Telegra h, Trolley'Wires, and other Uses, of which t e following is a speci- This invention relates to a sectional pole for telephone, telegraph, trolley wires, and other uses; and the same is to provide a p e of this class which is cheap in construction, strong and durable,

com aratively li ht in Wei ht, and embod P g i Y ing in its organization in t e main material that can be readily purchased in the market,

and thus facilitating the association of the parts thereof. p

The improved sectional pole is also convenient for transportationpurposes, as it may be shipped in sections or separate parts and.

- the pole is also extended to such an extent as to insure a better purchase in the ground, and thus render the complete pole more flexible above the ground support or anchorage, with increased strength as com ared to a tubular pole and considerably lig ter than the latter.

The pole is principally made up of angleiron or bar members which are held in connected relation by particular devices, and may be used either with or without a central tie bar or rod extending therethrough.

In the drawings, embodying the preferred construction of the pole in two forms, Fi re 1 is an elevation of a pole broken throng at several points and embodying the preferred features of the invention. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is 'a section on line 3 3 of Fig. 1. Fig. 4 is a section on line 4 4 of Fi 1, partially broken away. Fig. 5 is an eifiarged transverse vertical section through the base or foot of the pole. Fig. 6 is a sectional elevation of a portion of a pole embodying a modification 1n the construcprimary object of the. 0

tion. Fig. 7 is a horizontal section through the pole shown by Fig. 6. Fig. 8 is a detail of the ole illustrated by Figs. 6 and 7.

Simi ar numerals of reference refer to like parts throughout the several views.

The pole, as shown by Figs. 1', 2, 3, 4, and 5, is composed mainly of a series of angle iron members 1, with the angle edges thereof disposed inwardly,-as clearly illustrated by Figs. 2, 3, and 4. Each of the members 1 has at its lower end divergent right-angular feet 2,'which are secured to a base-plate 3 of any suitable dimensions and adapted to be disposed on a suitable ground-su port and anchored or secured in any suitablb manner. Gver the feet 2 a cover-plate 4 is applied and has angular recesses 5 at regular intervals therein to receive the members 1. This cover-plate forms a bottom support for cement grouting or other covering material that is introduced in or applied to the ole.

members 1 coupling and-reinforce collars 5 are applied and are slightly tapered to correspond to the upward and inward inclination of the members 1, which is preferred to reduce thepole toward its upper extremity and give the same greater stability, as will be readily understood. The coupling-collar 5 may also form the coverings for joints formed at intervals in the pole and in accordance with the length or height of the same. The collars 5 will be of dimensions corresponding to that portion of the pole over which they plates 6, which .serve as joint-'septums, and also as intermediate reinforcing means against any tendency toward inward crushing strain.

with angular recesses 7 to snugly-receive the members'l, and fitting in the members are inwardly-extending angular projections 8, formed as a art or secured to the collars or sleeves 5. n the upper ends of the members 1 a ring'or annulus 9 is applied and is similar in construction to the co lars 5 heretofore explained, said ring or annulus having inwardly-extendin "angular projections 10 fitting in the mem ers 1 and also having inside thereof a partition or septum 11, formed with recesses 12 to receive said members. On the top of the ring or annulus 9 a cap-plate 13 is secured, and this plate is intended to be 1 provided with suitable openings for receiving are fitted, and within the same are partitionsectional view showing the base for the form f At intervals throughout the length 0 the The partitions or septums 6 are each formed 5 leellar or band have slots 16 formed there- 20 a base plate or support, and the device or de 'where a securing-nut or other means may be?

in the form of the pole shown by 6 the main members 14: are in the form of bars se cured at their lower ends to a base 14", as

The members is adjacent to the point of application of into receive the upper and lower portions of links 17, which are pressed into place by the said collar or band 15, and provide an eX- tended surface for the bearing of such seller to permit the latter to serve its function in firmly holding the members is assembled relation. 'ihere are anumber of means of securing the lower ends of the members it to vices which Will be found most efiectivefoii this purpose Wiilbe adopted. The two forms of pole as thus far described can be manufactured and used for any pur pose Without further strengthening, or con necting means; but iumany instanees it is preferred that a tie-rod 18 be employed there with and extend through the center thereof, the said tiered being secured its lower end inthe center of the base 3 and passes upf' Wardly through openings 1?; in the partitions; 6 and 11, and also through the cap-plate 13,;

When this rod 18 is used, it will hold the cap-plate 13 firmly in place, as Well as the members 1 and i l, it bemg understood that said rod will also he used: with the form of the pole shown by Figs. 6: and 7, and,lurthern1ore, that a cap-plate or device similar to that shown by Fig. 1 may} also be applied to the form of pole. shown by Figs. 6 and 7. E i rom the foregoing it will be observed that} the pole in either of its forms may be readilconstructed and that the materials of whic it is composed may in the main be obtained. in the market, and thereby avoid the neces sity of a special preparation, thus materially reducing the cost of manufacture and at the same time rovide a strong and durable structure. The members assembled as exlained also provide a number of surfaces for eyingor holding cement filling or grouting in place therein'or thereover, and the partitions 6, as Well as the'bottom cover-plate 4, serve as a supporting means for the filling that may beintroduced into the pole as Well as intermediate reinforcing elements coopersting With the rings or clamping- bands 5 and 15 to fortify the pole structure.

sens-ea and the superiority thereof o er Wooden poles and the ordinary tubular poles is manifollr. and'will be readily appreciated by those skilled in the art. Furthermore, it is intended to form the pole of different sizes of angle and fiat iron or bar members.

What I claim is 1. A pole of the class set forth made up of a plurality of upwardly-extending, inwardly converging members, a base to which the lower ends of members are secured, taporing elainpingbands applied over the said members at intervals and provided with inwardly-projecting means equal in number to and engaging the said members, and a capplate fitting on the upper terminals of said members, the said cap-plate covering theupper end ofthe pole and providing means for the attachment of Wires and the like.
